[Higashino Mikan] Sunny May, Milking Season (Oppai na Natsuyasumi)

With no money for a love hotel and family waiting at home, Kaoru and her younger schoolmate Yuuzo slip away to a weathered barn deep in the countryside for their secret trysts. The sharp-tongued senpai teases that she is merely humoring her kouhai's fixation, keeping him at arm's length even as she promises him everything he wants, until a throwaway joke about saving milk 'for the baby' spirals into panic and an honest confession of love. Higashino Mikan's rural romance pairs breezy slapstick banter with a surprisingly warm, heartfelt finish.
